V1/T1 = V2/T2 Where temperature must be in Kelvins 67C + 273 = 340 K
So
140/340 = 50/T2 Find T2
340/140(50) = T2
T2 = 121 K or -152C

To find the new temperature, we can use the combined gas law formula: P1V1/T1 = P2V2/T2, where P is pressure, V is volume, and T is temperature. Since the pressure is constant, we can rearrange the formula to solve for the final temperature: T2 = (P1V1T2)/(P2V2). Plugging in the given values, we get T2 = (1 * 140 * (67 + 273))/(1 * 50) = 340.4 K.

Gases kept at constant temperature if its temperature is change from 50 celsius to 100 celsius by what factor does the factor change?
The temperature factor increases to 1.1547, approx.
Why if a gas is present at 27 Celsius its volume becomes doubled when temperature increases to 327 Celsius under constant pressure?
When a gas is heated, its particles gain kinetic energy and move faster, causing an increase in volume due to increased pressure against the container walls. The ideal gas law states that volume is directly proportional to temperature, so when the temperature doubles, the volume of the gas will also double assuming constant pressure.
What happens to volume if the temperature of a gas is decreased from 60 degrees Celsius to 30 degrees Celsius?
If the temperature of a gas is decreased from 60 degrees Celsius to 30 degrees Celsius, the volume of the gas will decrease if kept at constant pressure. This is in accordance with Charles's Law, which states that the volume of a gas is directly proportional to its temperature at constant pressure.
Rigid container holds hydrogen gas at a pressure of 3.0 atmospheres and a temperature of 2 degrees Celsius Whatwill bethe pressure if the temperature is raised to 10 degrees Celsius?
Using the ideal gas law, we can determine the new pressure by first converting the temperatures to Kelvin (273 K and 283 K, respectively). Plugging the values into the formula P1/T1 = P2/T2, the new pressure would be 3.16 atmospheres when the temperature is raised to 10 degrees Celsius.
What is the formula for the volume of a gas?
PV=Nrt where P is pressure V is volume N is the number of molecules r is 8.314472 J/K(mol) ( gas constant) t is the temperature in Celsius.
Does doubling celsius temperature double pressure?
No, doubling the Celsius temperature does not necessarily double the pressure. Pressure is influenced by various factors such as volume of the gas, number of gas molecules, and temperature, according to the ideal gas law (PV = nRT). Temperature is not the only factor affecting pressure.
What is the formula for finding pressure?
I suppose you mean the formula for the variation in pressure. The simplest expression of this is, at a fixed temperature,and for a given mass of gas, pressure x volume = constant. This is known as Boyle's Law. If the temperature is changing, then we get two relations: 1. If the pressure is fixed, volume = constant x temperature (absolute) 2. If the volume is fixed, pressure = constant x temperature (absolute) These can be combined into the ideal gas equation Pressure x Volume = constant x Temperature (absolute), or PV = RT where R = the molar gas constant. (Absolute temperature means degrees kelvin, where zero is -273 celsius)
What temperature is it in Bulgaria?
The temperature in Bulgaria is constant! 18 degrees Celsius!
When the pressure on a gas increases at constant temperature its volume?

What is the henrys law constant at 60 degrees Celsius and -10 degrees Celsius?
The amount of any given gas that will dissolve in a liquid at a given temperature is directly proportional to the partial pressure of that gas.
How does deacresing the temperature affect the volume of a gas?
If the amount of gas and the pressure remain constant, the volume will decrease by 1/273rd the original volume for each degree Celsius that the temperature decreases.
If temperature of a gas tripled what happens to the volume?
If the temperature of a gas triples (assuming pressure is constant), then according to the ideal gas law, the volume of the gas would also triple. This relationship is described by Charles's Law, which states that the volume of a gas is directly proportional to its absolute temperature at constant pressure.

A cylinder pf gas at room temperature has a pressure of p1. To what temperature Celsius would the temperature have to be increased for the pressure to be 2.2p1?
Using the ideal gas law (PV = nRT), we can see that pressure is directly proportional to temperature when volume and the amount of gas are constant. If we double the pressure (2.2p1), we need to double the temperature in Kelvin using the equation (T2 = 2T1). Converting this change in temperature to Celsius gives an increase of 273.15 degrees Celsius.
What volume is occupied by 2.0g He at 25 degrees celsius and 775 mmHg?
A fixed quantity of gas at a constant pressure exhibits a temperature of 27 degrees Celsius and occupies a volume of 10.0 L. Use Charles's law to calculate: the temperature of the gas in degrees Celsius in atmospheres if the volume is increased to 16.0 L
